HERNIAL TRUSS.

To all whom t may concern:

Be it known that I, CLEMENT SMITH, a citizen of the United States, residing at rIopeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in I-Iernial Trusses, Vof which the following is a specification.

My invention relates to hernial trusses of the general type illustrated in Patent No. 690,624, ranted January 7, 1902, to L. A. Smith. ts object is to substitute for the upward loop of the arch wire at the back, a pad that is pivoted or hinged to the arch wire in such manner that it has lateral flexibility with relation to the arch wire while maintaining substantially a constant position lengthwise of the wire; also to improve generally upon the means for fastening the arch wire to the truss-pad, and specifically to eliminate from such fastening device all loops or bends which would prevent the easy removal and application of the sleeve covering the arch wire, also to provide a simple, economical, strong, and durable fastening device that can be easily adjusted, applied,

yand removed, and that eliminates as far as possible projections likely to catch in the wearers clothing. And my invention comprises the parts, improvements, and combinations hereinafter set forth and claimed.

In the drawings accompanying and forming part of this specilication and in the description of the drawings I have shown my invention in its preferred form and what I deem to be the best mode of applying the principles thereof; but it is to be understood that within the scope of the appended claims, I contemplate changes in form, proportions, and materials, the transposition of parts, and the substitution of equivalent members, without departing from the spirit of my invention.

Figure 1 is an elevation of a hernial truss made in accordance .with the principles of my invention, somewhat in diagram. Fig. 2 is a view from the rear of the rear portion of the arch wire and the pads secured thereto. Fig. 3 is a sectional view through the line 3 in Fig. 2. Fig. 4 is an enlarged view of the front face of a pad in diagram and the front end of the arch wire, together with my improved fastening device, one of the screws being removed. Fig. 5 is a sectional view of the retaining plate through the line 5 in Fig. 4f. Fig. 6 is a sectional view of the parts shown in Fig. 4 through the line 6 Specification of Letters Patent.

in Fig. 4c. Fig. 7 is a face view ofthe front end of the arch wire. Fig. 8 is an end viewV vto said plate by any suitable means, as by the two screws 16, 16. The pad preferablyV overlaps the plate in all directions so as to protect the wearer from contact with the metal parts and projections.

Secured to the upper end of the plate is a stud 17 adapted to be engaged by the perforated end of the body strap 18. After the arch wire passes through the bearing 13 it is bent downwardly, as shown at 19, and to its lower end is attached (preferably flexibly) a pad 20, adapted to bear against the body of the wearer back of the hip joint. This pad also has a stud 21 adapted to be engaged bythe perforated end of the strap 22. Preferably the two body straps meet in front, as at 28, and continue thence to the pad 9 to which it is secured by means of the stud 25, substantially covering the fastening device.

The front end of the arch wire 10 is flattened, as shown at 26, the front face of the fiattened portion being preferably substantially in alinement with the front side of the normal or round portion of the wire, and it has a hole 27 therethrough.

2S is a retaining plate, preferably circular in contour and having its edge inturned, as shown at 29. It has a central opening 30, two oppositely disposed slots, arc shaped, near its periphery, and a slot 31 in its inturned edge. The latter slot is adapted for the reception, by close and snug fit, of the arch wire, the front face of whose flattened end lits against the inner surface of the retaining plate. 'Ihe holes 30 and 27 Y are brought into register, the inner threaded end 36 of the stud 25 is passed therethrough,

and the nut'l37 is then screwed onto the threaded end, clamping the flattened end of the arch wire firmly between the nut and the retaining plate. -The face of the trusspad is recessed, as shown at 33, for the reception o3t` the nut; and the nut is preterably round, at least as to that portion which engages in the recess, so that the parts that are held lirmly with the nut may oscillate thereabout. The retaining plate, and with it the arch wire, the stud, and the nut, are secured to the truss-pad by means oi' two screws 3st which pass through the slots 3L,

and into the pad.

ing device may be applied to and removed from tlietruss-pad while the device itself is thus iirmly secured to the arch wire.

By using the iiattened end of the arch wire with the fastening device, l am able to remove the sleeve l1 from and apply it to the arch wire, without bending or otherwise disturbing the latter', and also Vwithout cutting or otherwise injuring the sleeve. This is of special advantage be ause it is often necessary or desirable, for sanitary reasons, for repairs, etc., to remove the sleeve. Also my fastening' device may be adjusted, as indicated by the dotted outline 35 in Fig. i, by oscillating the retaining plate and connected parts in the recess 83, such movement being permitted by reason of the slots through which the retaining' screws engage. rlfhe adjustment is etiiected by slightly loosening the screws Set, then shitting the parts, and then screwingl down the screws firmly.

lilith regard to the upwardly extending' back pad, it will be noted that the downward bend 19 pre-vents the pad 'from slipping longitudinally upon the arch wire, the bend forming a stop. rthe advantage of so mounting the upwardly extending back pad upon the rear oi the arch wire so as to have forward and rcawvard oscillatory movement, is that by so doing this pad is made to contorni automatically to the wearer and to the movements oi' his body without such strain on the arch wire as would displace it or cause undue binding on the wearer.

YVhat l claim is:

l. in a hernial truss, the combination of an arch-wire having a flat iront end and a hole through the flat portion, a truss-pad having' a recess in its front face, a circular retaining plate having` a centrally-disposed hole, two oppositely disposed arc-shaped slots near its periphery, having its outer edge inturned and having a slot in said inturned edge ior the reception of the archwire, a stud having a screw-threaded inner end, said inner end extending' tlirough the centrally-disposed hole in the retaining plate and through the hole in the tlat portion ol" the arch wire, a nut engaging said inner end for clamping the liat portion between the inner face of the retaining plate and the nut, said stud having a bearing against the enter 'ace oi. said retainingl plate, said nut engaging in said recess in the truss-pad, and
